Which Animal Is Digging

The first way to determine the animals is to observe the type of holes. Moles will create tunnels and mounds, but skunks will flip over whole sections of turf. Skunks are looking for food, but moles are looking for food and shelter. Skunks, on the other hand, will dig precisely and will not leave deep holes in your lawn.

If you are careful enough, you will be able to determine which animal is digging your lawn.

Many animals can cause the same problem. However, if you suspect that skunks are the ones responsible, you have to do something about it. Many gardeners will have an issue with these animals unless something is done to reduce the number of grubs.;

Insecticides That Do Not Work On Grubs

Do not use products containing;ONLY;lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin for grub control.;Products containing only these ingredients will not work for grub control;because the active ingredient binds with organic material and will not move down to where the grubs are feeding. These products work well for above-ground feeding insects that live on the grass leaves or soil surface, but not for insects that feed on the roots. At one garden center a clerk showed us two products, one containing only permethrin and one containing only bifenthrin, when we asked for products to control grubs. Neither of the products listed grubs on the label printed on the bag and neither of the products would have controlled grubs.

How To Kill Active Grubs In Your Lawn

If you have active grubs in your lawn and seem to grow and invade your turf, it is time to take more serious precautions. Here is how to get rid of active grubs for good:

Apply pesticides

Grub control products that contain carbaryl, imidacloprid, and bifenthrin are effective at destroying active grubs in an established lawn. There are also granular and liquid grub killers on the market.

When using granular pesticides, it is best to apply them using your garden spreader. Dont forget to water to get the product down into the soil and kill the active grubs. When using a liquid pesticide, make sure to mix it with water. Spray the affected areas carefully .

When applying pesticides, it is essential to select the best and most effective product.

Apply nematodes

Another way to kill active grubs in your lawn is by applying nematodes. Beneficial nematodes are small worms that move under the turf, deep in the soil. They kill the grubs by releasing pathogens that attack them and kill them quickly.

When choosing nematodes, make sure to pick ones that work effectively against grubs. Mix them with water in your regular garden sprayer. Water your lawn accordingly to keep it moist at all types and always spray the nematodes in the evening.

Attract more birds

While this method is effective for getting rid of grubs, you have to be careful not to attract many birds because they can damage your lawn by digging up the turf and fighting over food.

Lawn Grubs: How to Identify, Get Rid of, and Prevent Them ...

While there are variations depending on which species of beetle they come from, the larvae tend to be stout, white-to-grayish with brown heads, about 3/4 of an inch to 2 inches in length. These lawn pests tend to curl up in a C shape at rest.

The grubs get their start when the adult beetles lay eggs in your turf, usually in spring. After the eggs hatch, the grubs evolve in three stages, with grub damage greatest in late summer, when you will see areas of your lawn thinning and yellowing. Later, irregular brown patches appear in your turf.

There are two major white grub species that cause problems in Ohio. Thats the Japanese beetle and the masked chafer, said Shetlar about his home turf.

Japanese beetle;grubs are widespread invasive insects, and their white grub larvae are bound to be found in lawns all over the country too, not just Ohio. Other chafer species besides the masked;chafer;beetles also lead to white grub;infestations and can establish in lawns beyond the states borders.

Other types of common lawn grubs around the United States include the larvae of the May and June beetles, green June beetle and the black turfgrass ataenius.

Its irrelevant which species it is, advised Shetlar. They cause the same kind of damage.

    A Summary For Successful Grub Control

    How to Kill Grubs in Lawn
    • Check the bag or bottle to determine what active ingredient the product contains.
    • Do not use products containing ONLY lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin for any phase of grub control.
    • Do not use preventive compounds such as clothianidin, thiamethoxam or imidacloprid now. Use them in June or July to control grubs that would be damaging turf in the fall. Applying them now will allow some of the chemical to leach through the turf or break down to the point that not enough insecticide will be there in July to control grubs.
    • The preventive compound chlorantraniliprole should ideally be applied in April or May to control grubs that would be damaging turf in the fall as it will take longer for the material to move to where the grubs will be feeding in July.
    • To kill grubs in the spring or fall, use carbaryl or trichlorfon.
    • Always wear rubber gloves and rubber boots when applying insecticides to turfgrass.
    • Make sure to irrigate the lawn with at least;0.5 inches of water*;and allow the grass to dry before allowing anyone or pets into the treated area. Irrigation is essential for the chemical to be most effective.
    • Store insecticide products in a locked cabinet not accessible to children.
    • Proper fertilization is important to prevent and allow the lawn to recover from grub damage.
    • Mow lawns immediately before applying an insecticide for grubs to remove weed flowers and protect bees.
    • Apply in spring or fall to active grubs.

    Controlling Lawn Grubs With The Best Grub Killer

    Early fall marks a peak feeding time for Grubs as they fatten up before winter. Once soil temperatures drop, Grubs dig in, heading 4-8 inches below ground, where they’ll stay snug until spring. That means early fall before temperatures tumble is a key time to go after Grubs, and as a result you can help prevent some of the most common lawn problems before they start.

    Pesticides for Grub Control

    For fall Grub infestations, apply a pesticide that’s labeled for Grub control and contains the active ingredient trichlorfon or carbaryl.


    Aeration As Grub Control

    If all you do to control grubs is aerate your lawn each spring, you’re still likely to see a reduction in the grub population. When your lawn has a thick thatch layer, it protects the grubs underneath from predators, such as birds, as well as pesticides. Pulling plugs out of the soil provides a conduit for pesticides to reach the grubs while it strengthens your lawn. When the grass is stronger and has deeper roots, it can withstand more root damage from grubs without dying.

    Management And Control Practices

    Cultural Control: Maintaining a healthy turf is important to culturally manage pest problems in any situation. This will involve proper soil preparation prior to turfgrass establishment, proper turfgrass selection for the site, proper installation, and using recommended management practices to assure a healthy lawn. However, grubs can damage the best-maintained turf.

    Biological Control: There are several products available that fall into the category of biological control. These types of pesticides will reduce pest populations using other organic or biological processes. The most common and widely used biological control of grub worms is milky spore disease. Milky spore disease is a soil inhabiting bacterium that is ingested by the grub during normal feeding. The bacterium then kills the grub and upon desiccation, the grub will release more bacterial spores into the soil. Milky spore disease is nontoxic to non-target species in the lawn. As with all biological controls, efficacy can be highly variable depending on the site and the environmental conditions at that site.

    Finally, there has been some research done on using the microbial biological control agent, Bacillus thuringiensis . Although there are several commercially available products of Bt for grub control, research has shown control to be marginal.

    Is there anything more damaging than grubs in your lawn?

    Few admire their looks. But, before dismissing them as nothing but gross menaces, grubs the larval stage of certain adult;beetles are common in lawns and do play a role in the natural order of things .

    David Shetlar is a professor emeritus with a doctoral degree in entomology at The Ohio State University. Hes also co-author of the comprehensive guide Garden Insects of North America,;plus other pest management tomes including Managing Turfgrass Pests.

    Shetlar chuckled brightly when asked if lawn grubs, commonly called white grubs, play a positive part in a lawns ecosystem. Everybody says grubs eat the grass roots, he said, but theres more to them than that. White grubs are eating the accumulated thatch and organic matter thats in the top inch of the soil profile.

    Theyre sort of natures de-thatchers, he added. But the problem is, theyre eating that thatch, they do eat the roots and the crowns , which kills the plant.

    Its when these de-thatcher populations grow out of control that the dreaded lawn damage takes place.

    Natural Ways To Get Rid Of Grub Worms In Your Lawn

    Grub worms damage your lawn by feeding on the roots, and eventually turn into adult beetles that eat the leaves of other prized plants in your garden. Many homeowners simply treat their lawn with a chemical grub control product, or grub killer, once or twice a year. But there are also a number of natural methods that can be effective ways to get rid of grub worms. Check out the following tips from our readers on how to get rid of grubs naturally.

    Q: I have white grub worms all over my garden and I hate to use pesticides. Are there any natural methods to get rid of them?

They come on a sponge that you soak in water, put in a sprayer and spray your dirt or lawn. They will multiply over time and continue to kill grubs. They have nematodes that seek and destroy flea larvae too. Here’s what one reader says about his experience with nematodes: “Works great. Did my yard last year, my dogs never have fleas unless we go someplace else. The nematodes for grubs work equally as well. Had them in my compost pile, wiped them out. No more grubs!” .

    Answer 5: Other readers have seen results using neem oil. Mix as directed with water and spray affected areas of your lawn to deter beetles from laying eggs, as well as keep grubs from feeding. .

    Preventive Insecticides That Will Prevent Grub Damage Next Fall And Following Spring

    These products are used to prevent future grub problems, not to control the grubs present in the lawn in the spring. They will not work on grubs found in the lawn from the middle of October through the middle of May. However, when applied in June or July they provide excellent protection against the next generation of grubs. So, if you need to apply the preventive insecticide;BEFORE;the grubs are there, how do you know if you need to use an insecticide or not? If you confirmed grub damage the previous fall or spring, meaning you found lots of grubs, then you may want to use a preventive insecticide for one or two years to build a more dense turf that will be tolerant of grubs. If you have treated for several years and you do not see evidence of grubs in your lawn or in the neighbors lawn, it may be time to stop treating. There is an erroneous philosophy being perpetuated that because we have European chafers and Japanese beetles in the area, it is necessary to treat every year or your lawn will be damaged by grubs.;This is not true.

    In addition, grub control products that contain the active ingredient chlorantraniliprole are safe for bees, even when weed flowers are sprayed. Finally, avoid spray drift or granular spreader drift to flower beds when applying thiamethoxam, imidacloprid, clothianidin or any insecticide for grubs other than chlorantraniliprole
